OVEN-DOOR HI1IGE.

T0 aZZ wkom z't may concern:

.B e it known that I, BENiJ'MIN" MEAOHAM, a citizen of the United States, 'esidin at Lrain, in the county of Lorain and tate of Ohio, have invented oertain new and useful Improvements in Oven:

Door Hinges, of vvhich the fol lowing is &

speoifioation, reference being had therein to the aeeompanying drawing.

This invention relates to improvementsin oven door hinges, and the primary purpose of the present invention is to construct the hinges so that they are entirely oonoealed when the oven door is olosed.

A further object of the present invention is to looate an oven door hanger or hinge at the inner side of the frame of the oven, whereby the sarne-when closed is completely concealed.

Another object of the present invention is to provide a hinge or snpporting niember for anoven door, whieh when the door is olosed it is wholly ooncealed, and when the door is open only one end of the support or hinge is visible.

A further object of. the present invention is to make a hinge for oven.doors whieh is ssentially L-shaped, the longleg of the L within the the short leg of the support or hinge hinged to the door, whereby the said hinge or supporting member is wholly eonoealed when the door is closel.

A further ob'ect of thepresent invention is to provide ainge or supporting member substantially of the L pivoted to the inner sides of the oven or stove, and the short leg passin through en opening in the Wall or frame o the stove and pivoted to the oven door, and

a spring looated between the long leg of the hanger and the frame of the stov.

Anot her object of the present invention is with its spring m a flue of the oven, whereby the spring 1s not subje"cted to the extreme heat of the oven and therby the temper of the spring is not destroyed.

Further objects of the present invention tWooor oven, the;d0ors shown L-shaped, With the long leg will appear from the following description and disolosure. ln the accompznying drawings,

Fi re 1 is a. front elevation showing a the hinges or supports for in dotted lines.

Fig. 2 is a sectional view on the line 2-2 of Figure 1, the upper door being showri open and the lower door closed.

Fig. 3 is a horizontl seotinal view on the line 3-3 of Figure 2.

Fig. 4 is a front e levation partly in seotion of one corner of the door.

In the oonstruction herein shown there are no parts of the hinge or support that is at a1l visib1e when the oven door is closed, thus n1akingthe front of the stove free from the usua l type of external hinges and fastening devices therefor, which are linsight1y and necessarily more ex ensive to manufaeture than the hinges of t is applioation.

In the drawings, 1 is a frame for the ing closeql by a suitably shaped oor 3. In

the form of door here shown, the lower corners 4 someWhat extend beyond the door,"

;but I desire it to be understood that the door frame of the oven or s tove, and

may be of the same shape entirely around its edge without depart1n from the idea here disolosed. A1so the oor. here shown has its edge made U-shaped, as shown at 5, with an internal portion 6, whioh letter may or may not beenameled.

The door-frame 1 is made sufiioiently large to extend over a vertical flue 7, for a purpose to be presentl exp1ained.

In carrying forwar rny present imprvement, I prov1de a supporting member 8 that has ts upper end hinged at 9, to a suitable exterision 10 from the frame 1 of the ovendoor opening 2. This member 8, as here shown, extends downw ardly "and has its to locate the su porting or hinged member 1 ower end 9 pivotally connected at 10 with the 8 foijeach. corner of the door. In the forni here shown, the member 8 preferably extends upvvard within the flue 7, though I desire it to be understood that it may extend downward in the said flue Without departing from the scope of the present invention, since the flue 7 extends fro'm top to bottom of the oven.

For the purpose of easing the door in its downward movement, I provide a suitable spring 12, Which is coiled and located loetween the member 8 and the frame 1. Th1s spring is compressed when, the door is opened, whereby it opensagamst some pressure of the spring, and the spring serves to hold the doorclosed.

The lower edge 13 of the U-shaped part 5 engages the lower portion 9 when the door is open, whereby it is held in a hor1zontal position and is not permtted to svv1ng beyond that position. It will be understood that the edge 13 regulates the amount of outward movement that the door ma be peimitted, and, therefore, the angle 0 the door when opened is regulated by the engagement of the part 13 with the under edg of the part 9 of the hinge or supportmg member 8.

Preferably the lower end 9 of the hinge member 8 extends inward at an angle to the part 8, and as shown, the part 8 is thereb preferably. made substantially L- shape in contour.

When. the door is closed the U-shaped art 5 isheld against the frame 1. Hence 1n opening the door, the lower edge 13 sl ides on the frame, and for the purpose of facilitating this sliding movement, I provide the door-frame with a downwardly extending rib 14e, with which the edge 13 of the U-shaped part engages when the door is moved to open pos1tion.

I desire it to be understood that the fram of the oven A or stove, may be made in any desred form, but preferably it has at opposite sides of the door frames vertically ar ranged flues 7, in whch flues the hangers 8 are located for the purpose of protectng the spring 12 and the hangers from the, heat withm the oven, as will be readily understood. In that manner the springs are not subjected to the intense heat of the oven and the temper of the spring is not destroyed.

I also desire it to be understod that the oven and the surrounding frame, and the shape of the door may be substantially of any desired construction without departing from the invention herein .disclosed.

I also desire it to be understood that the specfic constructlon of the inventin here disclosed may be varied so long as the change is within the spirit and scope of the applended claims.

aving thus described my invention, what I ctlaim and desire to secure by Letters Paten is:
